I think you get blinking anything on a page and it drives away potential users. Every book on interface design I've read (and I've read more than a few) agrees that blinking is a big NO. You reserve it for use in really important situations, you don't spatter it about over pages in the mistaken belief it creates interest.
To return to your topic, this is just one symptom of many that this site needs a major overhaul, both in presentation and in usability.
Any ideas on how to convince the site owners?
